Set this over a saucepan of simmering water until the chocolate melts, then remove from the heat. Next, stir in 75g caster sugar, a tablespoon of rosewater and two eggs. Using a handheld electric beater, whisk for five minutes. Lastly, whisk in 250g mascarpone for a few seconds, until combined. Divide between the four glasses and chill. Then crack open the Chablis. Happy Valentine’s!
